Approximately 30,000 cars pass through the intersection of Karcher Road (Idaho Hwy 55) and Middleton Road each day. This intersection is one of the most crash-prone sites in Idaho and rapid development has resulted in greater traffic congestion.

Currently, both Karcher Road and Middleton Road are two-lane rural roadways at the intersection area and there are no bicycle lanes or continuous sidewalks within the project limits.

ITD and the City of Nampa are partnering to rebuild this intersection to improve safety and reduce congestion.

Project Description

The project will rebuild the existing Karcher Road and Middleton Road intersection. On Karcher Road improvements will be made from just west of Elijah Drain to the vicinity of Sundance Street. On Middleton Road improvements will be made from Aries Drive to the vicinity of Hailey Avenue.

Improvements will include adding more lanes, sidewalks, curb, gutter and a new traffic signal.

Design Activities

Ten proposed alternatives were initially discussed for this project. Four alternatives were carried forward for further evaluation and presented to the public for review and comment in August 2012. ITD has been working to finalize design plans for the project, and in early 2014 the planned improvements were presented at a public open house and online public meeting.
